[0041] In order to further understand the content of the utility model, the utility model is described in detail in combination with the drawings and examples.

[0042] The structure, proportion, size and the like shown in the drawings of the specification are only used to cooperate with the content disclosed in the specification, to be understood and read by those skilled in the art, and do not have technical significance to limit the conditions that the present application can be implemented. Any modification of the structure, change of the proportional relationship or adjustment of the size, without affecting the effect and purpose that the present application can produce, should still fall within the scope of the technical content disclosed by the present application.

[0043] Figure 1 A slow descent storage box is shown, the cover plate 2 is in an open state, a boost support rod 3 is arranged between the box body 1 and the cover plate 2, and a slow descent mechanism 4 is arranged close to the hinge joint of the boost support rod 3 and the box body 1.

[0044] Figure 2 The local method structure of the slow descent mechanism 4 and the frame strip 11 connection part is shown.

[0045] In combination Figure 1 , Figure 2 The slow descent storage box of the embodiment comprises a box body 1 and a cover plate 2 hinged at the top of the box body 1, and a boost support rod 3 is arranged between the box body 1 and the cover plate 2. The boost support rod 3 can be telescopic, and provides auxiliary support force when the cover plate 2 is opened upward. The cover plate 2 and the box body 1 can be metal pieces, the left edge of the cover plate 2 is hinged with the box body 1, and the cover plate 2 can be turned upward to open the box body 1.

[0046] The boost support rod 3 can be a gas spring, or a lifting mechanism using hydraulic pressure, or a spring auxiliary mechanism, etc. The boost support rod 3 can provide auxiliary support force when the cover plate 2 is opened upward, reduce the stress, and make the cover plate 2 stay in the open state without falling back.

[0047] The box body 1 has a frame strip 11 at the top for strength and forming a support; the hinge for turning the cover plate 2 can be connected to the frame strip 11. The other sides of the box body 1 can be provided with box plates 12, which can adopt different structural forms.

[0048] In some embodiments, the box body 1 is composed of a frame of frame strips 11 and vertical rods 13, and the frame strips 11 and the vertical rods 13 are both profile structures, and are connected with the box plates 12 by bolt splicing.

[0049] In the embodiment, the frame 11 on the top of the box 1 is provided with a slow descent mechanism 4, which has a sleeve 42 vertically installed on the frame 11, and a flexible slow descent device 41 axially inserted into the sleeve; the top end of the flexible slow descent device 41 protrudes from the upper surface of the frame 11. The flexible slow descent device 41 is an independent elastic buffer mechanism, such as a gas spring, a hydraulic buffer cylinder, or a buffer piece composed of a spring.

[0050] When the cover plate 2 is opened, the assisted support rod 3 provides assistance to open and maintain the cover plate 2 in the open state. When the cover plate 2 is closed to a certain angle from the open state, the top end of the flexible slow descent device 41 contacts the inner surface of the edge of the cover plate 2 and maintains the contact to the closed state, and the slow closing of the cover plate 2 is realized by the elastic resistance of the flexible slow descent device 41, so as to avoid the noise caused by the rapid pressing of the cover plate 2 on the box 1.

[0051] The angle at which the cover plate 2 contacts the flexible slow descent device 41 can be set by the protruding height of the flexible slow descent device 41. In combination Figure 1 , the flexible slow descent device 41 can be located at the middle position of the frame 11 or close to the right side of the frame 11. The top end of the flexible slow descent device 41 can contact the cover plate 2 when the angle of the cover plate 2 relative to the frame 11 is 10°-25°.

[0052] The existing noise reduction mechanism mostly only sets an independent buffer between the box and the cover plate, for example, only sets a gas spring, which uses the buffer effect of the gas spring to simultaneously achieve the purpose of support and slow descent. However, in actual use, the gas spring can assist in supporting, but when descending, only the air pressure resistance can be used to resist the external force applied to the cover plate 2 at the initial angle, and after falling to a certain angle, the support force of the gas spring is much smaller than the gravity of the cover plate 2, which will cause the cover plate 2 to rapidly impact the box 1. The present embodiment combines the assisted support rod 3 and the slow descent mechanism 4, so as to effectively avoid the impact and reduce the noise on the basis of providing the support force.

[0053] The gas spring referred to in the present application refers to a telescopic mechanism using a gas cylinder and a piston rod relying on inert gas, and the specific form can refer to the existing gas spring structure.

[0054] In an embodiment, the assisted support rod 3 can be hingedly connected to the cover plate 2 at one end and slidably connected to the box 1 at the other end. The assisted support rod 3 can also be hingedly connected at both ends, for example, the assisted support rod 3 is a gas spring support rod, one end of which is hingedly connected to the frame 11, and the other end is hingedly connected to the frame of the cover plate 2.

[0055] Further, the hinge point of the assisting strut 3 and the box body 1 is located inside the frame strip 11, so that the assisting strut 3 is arranged in an inclined manner when the cover plate 2 is in the closed state. The cover plate 2 is located above the frame strip 11, and the hinge point of the assisting strut 3 and the box body 1 is located inside the frame strip 11, so that it is lower than the upper surface of the frame strip 11 and lower than the hinge point at the other end, avoiding being locked and unable to be opened when falling.

[0056] On the basis of the embodiment, the length of the slow-falling mechanism 4 from the hinge end of the cover plate 2 is not less than 1 / 3 of the total length of the frame strip 11, for example, in the range of 1 / 3 to 2 / 3, and preferably in the middle part of the frame strip 11.

[0057] In combination with FIG. 3, Figure 4 For the elastic slow-falling device 41, in some embodiments, the elastic slow-falling device 41 includes a cylinder body 411 and a piston rod 412, and the relative movement between the cylinder body 411 and the piston rod 412 can be achieved by using air pressure, hydraulic pressure or spring to achieve the buffering effect. As a specific embodiment, since the piston rod 412 is thin, in order to ensure reliability, the piston rod 412 is located in the sleeve 42, and the cylinder body 411 protrudes from the sleeve 42 at the top to contact the cover plate 2 for buffering. More preferably, a rubber material buffer head 414, such as a rubber pad or a silica gel pad, can be arranged at the top of the cylinder body 411.

[0058] In order to facilitate installation, the sleeve 42 can be directly inserted into the opening of the frame strip 11, or a rubber sleeve can be added in the opening of the frame strip 11 to prevent the sleeve 42 from falling off the frame strip 11.

[0059] In an embodiment, the pipe barrel 421 of the sleeve 42 has a circumferentially arranged limiting rib 423, and a protrusion 413 matched with the limiting rib 423 is arranged on the elastic slow-falling device 41 to block the elastic slow-falling device 41 from being separated upward from the sleeve 42. For example, two arc-shaped limiting ribs 423 are arranged axially, and the limiting ribs 423 are inwardly recessed. The protrusion 413 arranged on the elastic slow-falling device 41 can also have multiple protrusions in the circumferential direction, so that it can resist the limiting rib 423 to prevent the elastic slow-falling device 41 from falling off the sleeve 42.

[0060] For household storage boxes, for example, garbage cans, convenient transportation and easy installation are required, so the frame strip 11 is mostly hollow profiled material. In order to be able to be quickly installed, the top of the sleeve 42 has an outwardly turned edge, the bottom of the sleeve 42 passes through the insertion hole of the frame strip 11, and a flexible clasp 43 is sleeved. The turned edge can be formed by turning the top edge outwardly, or a protrusion can be formed at the top end, which can limit the sleeve 42 from falling off the opening of the frame strip 11.

[0061] For this storage box, it is generally placed vertically, and when installed, the sleeve 42 is inserted into the frame strip 11, and it will not fall upwards. But in use, it is found that if the buffer head 414 is used, in some areas, the rubber will partially melt due to high temperature, showing a certain viscosity, and then the top end of the elastic slow descending device 41 will be bonded with the cover plate 2, and then when the cover plate 2 is opened, the sleeve 42 will be separated upwards from the frame strip 11.

[0062] In order to avoid this situation, it is conceivable to set a nut at the bottom of the sleeve 42, which has a very stable effect.

[0063] And in the present embodiment, a non-threaded fixing form is adopted. For threaded structure, although it can realize quick installation and has a very stable effect. But considering the actual use, if the threaded structure is adopted, the sleeve 42 needs to be processed twice, which will affect the whole process. In the present embodiment, the bottom of the sleeve 42 passes through the hole in the frame strip 11, and the flexible clasp ring 43 is sleeved. By adopting the clasp ring 43 structure, the sleeve 42 does not need to be processed twice, and it does not need to use external tools when installing, and the use effect is good.

[0064] The clasp ring 43 adopted includes a ring seat 431, which can be made of rubber or silicone material, and can be sleeved on the pipe barrel 421 of the sleeve 42 when in use.

[0065] In another embodiment, the clasp ring 43 adopted includes a ring seat 431 and a necked cap 432, the necked cap 432 is a reverse tapered structure, and the bottom of the necked cap 432 is connected with the ring seat 431 as a whole. In order for the ring seat 431 to clamp the pipe barrel 421, the inner diameter of the ring seat 431 is not greater than the pipe barrel 421, and the necked cap 432 can be guided during installation to realize quick installation.

[0066] Further, the necked cap 432 is a thin-walled structure, and the reverse tapered structure forms an upward horn, when the sleeve 42 is pulled upwards, the necked cap 432 will be pressed downwards, thereby forming a greater friction force to avoid the sleeve 42 from being separated. Further, the edge thickness of the necked cap 432 is not greater than 3mm, for example, 1.5-2.6mm.

[0067] Figure 5 A specific storage box structure is shown, which is a double-box garbage can. As a specific application, the storage box can also be a single-box garbage can, or a household parcel box, etc.

[0068] The above describes the utility model and its embodiments in a schematic manner, and the description is not restrictive, and the drawings only show one of the embodiments of the utility model, and the actual structure is not limited thereto. Therefore, if a person of ordinary skill in the art is inspired thereby, without departing from the creative concept of the utility model, similar structural modes and embodiments are designed without creativity, and all should belong to the protection scope of the utility model.
